To provide a thin and lightweight round knitted fabric for a heater, which has sufficient elasticity and high heat generation efficiency, can follow the deformation when used for seats, etc.SOLUTION: A round knitted fabric 10 for a heater is formed by knitting conductive fibers 11 and non-conductive fibers 12, and the conductive fibers 11 has an electric resistance value generated efficiently in the range of 102 Ω/m to 107 Ω/m when energized. As a result, a high energization heat generation efficiency can be obtained, and the round knitted fabric for the heater has excellent elasticity peculiar to the knitted fabric. Further, since the conductive fiber 11 is provided with a welt portion 14 in which the conductive fiber 11 is linear between tack stitch portions 13, the length of the bent portion of the conductive fiber 11 is shortened, and while maintaining elasticity, the overall electrical resistance can be reduced. Further, by using false twisted yarn as the non-conductive fiber 12, the elasticity can be further increased.SELECTED DRAWING: Figure 1

    【課題】十分な伸縮性と高い発熱効率とを有し、座席シート等に用いた場合の変形にも追従でき、薄くて軽量なヒーター用丸編地を提供する。【解決手段】ヒーター用丸編地10は、導電性繊維11と非導電性繊維12が編成されてなり、導電性繊維11は通電した際に効率良く発熱する102Ω/m〜107Ω/mの範囲内の電気抵抗値を有している。これによって高い通電発熱効率が得られるとともに、編地に特有の優れた伸縮性を有するヒーター用丸編地となる。また、導電性繊維11がタック編目部13の間において直線状になるウエルト部14を備えているため、導電性繊維11が屈曲する部分の長さが短くなり、伸縮性を保ちながら全体の電気抵抗を小さくすることができる。さらに、非導電性繊維12として仮撚り加工糸を用いることで、伸縮性をより大きくすることができる。【選択図】図1
